Abstract

Abstract The soldering tool provides a working tip formed to contact the multiple pins of an integrated circuit. The working tip can be in the form of a channel to contact the outside of the pins for integrated circuits soldered in printed circuits boards. The working tip may also be a rectangular block partially chamfered for contacting the inside of an inverted integrated circuit for soldering or desoldering the integrated circuit from a printed circuit containing rows of pins. Biased clamping jaws are slidably fastened to the soldering tool for gripping the integrated circuit to bring the working bit into and out of contact with the plurality of solder junctions on the integrated circuit without releasing the clamping jaws.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 141 words
A soldering tool for soldering a component to a printed circuit board at a plurality of junctions comprising: a handle; a heating element within said handle capable of providing sufficient heat to melt solder; a working bit heated by said heating element and shaped to contact the plurality of solder junctions of the component at one time; and an extractor including clamping jaws formed to clasp the component adjacent to said working bit, biasing means for urging said clamping jaws towards each other, and a pair of lever extension arms fastened to said clamping jaws for easily overcoming said biasing means, said extractor fastened to said handle for slidable motion along the longitudinal axis of said handle to bring the plurality of solder junctions of said component into and out of contact with said working bit without releasing said clamping jaws.
Claim 2
Dependent Claim 141 words
A soldering tool for soldering a component to a printed circuit board at a plurality of junctions comprising: a handle; a heating element within said handle capable of providing sufficient heat to melt solder; a working bit heated by said heating element and shaped to contact the plurality of solder junctions of the component at one time; and an extractor including clamping jaws formed to clasp the component adjacent to said working bit, biasing means for urging said clamping jaws towards each other, and a pair of lever extension arms fastened to said clamping jaws for easily overcoming said biasing means, said extractor fastened to said handle for slidable motion along the longitudinal axis of said handle to bring the plurality of solder junctions of said component into and out of contact with said working bit without releasing said clamping jaws.
Claim 3
Dependent Claim 32 words
The soldering tool of claim 1 wherein said working bit is shaped in a substantially rectangular block form partially chamfered on the portion of the working bit contacting said plurality of junctions.
Claim 4
Dependent Claim 32 words
The soldering tool of claim 1 wherein said working bit is shaped in the form of a channel to contact the plurality of junctions of the integrated circuit within the channel form.
Claim 5
Dependent Claim 193 words
In a soldering tool for soldering a component to a printed circuit board at a plurality of junctions, said soldering tool including a handle and a heating element within the handle capable of providing sufficient heat to melt solder, the improvement comprising: a working bit heated by the heating element and shaped to contact the plurality of solder junctions of the component at one time; an extractor including clamping jaws formed to clasp the component adjacent to said working bit, biasing means for urging said clamping jaws toward each other, and a pair of lever extension arms fastened to said clamping jaws for easily overcoming said biasing means; a pair of yokes fastened to the handle and spaced a distance apart; at least one guide pin fastened between said yokes; and a spacer fastened to said extractor and slidable along said guide pin along an axis longitudinal to the axis of said handle; said yokes, guide pin and spacer defining the longitudinal travel of said extractor such that that the plurality of solder junctions of said component is brought into and out of contact with said working bit without releasing said clamping jaws.
Claim 6
Dependent Claim 193 words
In a soldering tool for soldering a component to a printed circuit board at a plurality of junctions, said soldering tool including a handle and a heating element within the handle capable of providing sufficient heat to melt solder, the improvement comprising: a working bit heated by the heating element and shaped to contact the plurality of solder junctions of the component at one time; an extractor including clamping jaws formed to clasp the component adjacent to said working bit, biasing means for urging said clamping jaws toward each other, and a pair of lever extension arms fastened to said clamping jaws for easily overcoming said biasing means; a pair of yokes fastened to the handle and spaced a distance apart; at least one guide pin fastened between said yokes; and a spacer fastened to said extractor and slidable along said guide pin along an axis longitudinal to the axis of said handle; said yokes, guide pin and spacer defining the longitudinal travel of said extractor such that that the plurality of solder junctions of said component is brought into and out of contact with said working bit without releasing said clamping jaws.
Claim 7
Dependent Claim 32 words
The soldering tool of claim 4 wherein said working bit is shaped in a substantially rectangular block form partially chamfered on the portion of the working bit contacting said plurality of junctions.
Claim 8
Dependent Claim 32 words
The soldering tool of claim 4 wherein said working bit is shaped in the form of a channel to contact the plurality of junctionS of the the component within the channel form.
